What survives at Lisfunshion, on a north-facing slope just below the crest of a hill in undulating Tipperary pastureland, is the southern arc of what was once a roughly circular enclosure, its northern half levelled at some point, leaving behind only the geometry of absence to suggest what the whole once looked like.

Ringforts, known in Irish as raths, were the most common form of rural settlement in early medieval Ireland, typically consisting of a circular earthen bank and outer ditch enclosing a farmstead. The example at Lisfunshion follows that pattern, at least in what remains. The surviving southern half measures 27 metres east to west, defined by an earthen bank roughly 3.9 metres wide at its base and narrowing to about 1.8 metres at the crest. The internal height of the bank reaches just under three-quarters of a metre, the external face slightly more at a metre. Beyond it runs a flat-bottomed outer fosse, the defensive ditch that would have reinforced the enclosure, here measuring 2 metres wide and 0.7 metres deep. The structure does not appear on the first edition Ordnance Survey six-inch map of 1840, though by the 1907 edition it is indicated as a roughly circular area, suggesting it was recognisable as an earthwork even in partial ruin by the early twentieth century.

The interior is now heavily overgrown with brambles, and scrub has taken hold along the top of the surviving bank, which makes close inspection difficult. The earthwork sits quietly in ordinary farmland, easy to overlook and easier still to misread as a natural rise in the ground.
